This B450M-HDV R4.0 gaming motherboard utilizes the next-generation Hybrid Digi Power design to bring precise control and smooth power. As well as ensuring efficient and clean power delivery to the CPU, the stability and lifespan of the motherboard are also greatly increased.
The motherboard comes with AMD StoreMI technology, a powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive. AMD StoreMI technology “combines” those two types of storage into a single drive and automatically moves the data you access most frequently to the SSD, so you can get the best of both worlds.
The PCIe Gen3 x4 Ultra M.2 interface accelerates data transfer speeds up to 32Gb/s. In addition, it also supports SATA3 6Gb/s M.2 modules and is compatible with ASRock’s U.2 kit to install some of the world’s fastest U.2 PCIe Gen3 x4 SSDs. ASRock put solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stability and ensure a longer lifetime.
